MP28162 Overview
The MP28162 is a high-efficiency, low quiescent current (IQ), buck-boost converter that operates from an input voltage (VIN) exceeding, below, or equal to the output voltage (VOUT). The device provides a pact solution for products powered by single-cell Li-ion or multicell alkaline batteries, where VOUT is within the battery voltage (VBATT) range. Current-mode control and the fixed pulse-width modulation (PWM)...
